Obnoxious noise maker will scare your neighbors

This “obnoxious noise maker” called the “Ubnox-O-Phone” by its maker is a combination of a sound generator and Ruby Guitar Amp who’s schematic can be downloaded from their site. The whole project only cost $35 so it’s a pretty cheap way to annoy people. Check out the video at the link below.
